Title: Measuring device for stop-down performance
Inventor: TAKANO KATSUAKI
IPC: G03B43/00
Filed: 1984-09-20
Abstract: PURPOSE:To set a criterion of brightness and to make an equal-level judgement for various stops by converting light passed through a stop to be checked into an electric signal through a photoelectric conversion part, digitizing and processing it, and making its display. CONSTITUTION:The light passed through the stop to be checked is converted through the photoelectric conversion part into the electric signal, which is supplied to a processing part 18. A light quantity signal is amplified by a preamplifier 21, passed through a sample holding circuit 22, and converted by an A/D converter 20 into a digital signal. A time base 23 which is oscillated with a clock having a period of minimum resolution determined by measurement precision is led out as an output through a gate 25 only after a main switch is operated, and data stored in a memory 26 stored with the output of the converter 20 is stored so that the resolution of the base 23 is regarded as precision. The time of a rise from a stable level to a set level or decrease is calculated by a CPU27 from the data stored and displayed on a display device 29 as a stop- down end time to improve operativity, thereby preventing an error in measurement.

Title: Dephosphorizing agent and production thereof and dephosphorizing method of discharge water
Inventor: KURAMOCHI RIE
IPC: C01F5/30
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To obtain a dephosphorizing agent capable of producing it at a low cost and easy in handling by preparing the dephosphorizing agent consisting of a gelled product of MgCl2 as an effective utilizing composition. SOLUTION: The dephosphorizing agent used to purify waste water, discharge water, contaminated water, and sewerage water, etc., containing a phosphorus compound, is prepared by using the gelled product of MgCl2 . A suspension liquid of calcined magnesia is added hydrochloric acid, then is stirred at a state as it is or at a heated state and is left as it is, thus the solution gradually loses fluidity to become a gelled state, and this product is used as the gelled product. In a dephosphorizing treatment of the phosphorus-containing discharge water, the gelled product of MgCl2 is added to the discharge water to treat so as to allow the liquid to react in an alkaline region. Thus, the phosphorus present in water to be treated is adsorbed or a phosphorus quantity in the liquid is reduced by reacting with the phosphorus.

Title: Manufacture of storage battery having spiral plate
Inventor: TANIGUCHI ISAO
IPC: H01M50/528
Filed: 1984-09-25
Abstract: PURPOSE:To prevent a heated welding electrode from touching the separator by inserting a cylindrical electrode guide into the central space of the rolled plate group prior to placing a welding electrode in the central space, and bringing the welding electrode into contact with a negative tab through the electrode guide. CONSTITUTION:A cylindrical electrode guid 21 is inserted into the central space 15 of the rolled plate group installed in a metallic case 20. One end of the cylindrical electrode guide 21 is slantly cut in order to facilitate its insertion into the space 15. It is preferable that the electrode guid 21 be formed by a material which is hardly heated. After insertion of the electrode guide 21 is completed, a welding electrode 22 is placed in the electrode guide 21 to bring the pointed end of the welding electrode 22 into contact with a negative tab 19. After that, spot welding is performed by current feeding while using the welding electrode 22 to press the tab 19 upon the bottom 20a of the metallic case 20. During the above process, it is possible to prevent the welding electrode 22 from directly touching the separator 11.

Title: Inverter circuit for fluorescent lamp
Inventor: MORI IICHIRO
IPC: H05B41/24
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To prevent high voltage from being applied to both electrodes during the time for preheating the filaments of a fluorescent lamp, and thereby obtain the optimum starting characteristics of the fluorescent lamp by letting a TRIAC be energized so as to allow the fluorescent lamp to be started after a set preheating time has elapsed. SOLUTION: Since the gate circuit of a TRIAC 8 is not triggered until a timer circuit 13 is timed up, high voltage is developed at the main coil 5 of an inverter transformer 3, however, no voltage is applied to both electrodes of a fluorescent lamp 14 at all because the TRIAC 8 is in an isolated condition. Therefore, electric power is fed only to the filaments 15 and 16 of the fluorescent lamp 14 from the inverter transformer 3 so as to preheat the filaments 15 and 16 of the fluorescent lamp. When the filaments 15 and 16 are preheated, thermal electrons are started so as to be developed, and after the thermal electrons has been sufficiently developed, the timer circuit 13 is timed up, so that the gate circuit of the TRIAC 8 is thereby triggered.  When the TRIAC 8 is energized, high voltage is applied to the fluorescent lamp 14 from the main coil 5 of the transformer 3 through a ballast capacitor 7 and the TRIAC 8.

Title: Magnetic substance detector
Inventor: MURATA YOSHIYUKI
IPC: G01V3/08
Filed: 1989-07-31
Abstract: PURPOSE:To reduce the effects of magnetic noises by outputting a magnetic substance detection signal from an abnormality judging means when the difference between the detected magnetic field and an ordinary magnetic field at this position on the earth exceeds a specified value. CONSTITUTION:When a magnetic substance which is not stored in a magnetic map memory 5 is detected with a magnetic-field detector 1, an ordinary magnetic field (m) is not changed for a time DELTAt even if a detected magnetic field M starts changing. An abnormality judging means 6 actuates a magnetic substance presence judging means 3 and outputs a magnetic substance detection signal into a processing system B. At this time, the magnetic substance presence judging means 3 computes the tolerance ratio between the waveform of the detected magnetic field M and a reference waveform. The presence or absence of the magnetic substance is judged based on the tolerance ratio, and the magnetic substance detection signal is outputted to the processing system B. The input signals from the magnetic substance presence judging means 3 and the abnormality judging means 6 are recorded in the processing system B. When the magnetic substance detection signals are inputted from the means 3 and 6 at the same time, warning is issued. Therefore, the effect of magnetic noises can be reduced.

Title: Cooker
Inventor: KATSUHARA KENJI
IPC: F24C15/16
Filed: 1990-07-25
Abstract: PURPOSE:To prevent leakage of water from inside a cooking chamber in an easy manner by a method wherein a voltage is applied between electrodes of a shaft member consisting of a piezoelectric material to make the outer circumferential part of the shaft member partly undergo repeated expansion and shrinkage so as to cause the shaft member to slide on the inner surface of a bearing with an effect to rotate a turntable. CONSTITUTION:A microwave radiation is emitted from a magnetron 19 into a cooking chamber 13 and a turntable 15 is rotated. The turntable 15 is driven by a drive circuit (voltage-applying means) 28 which applies a voltage between electrodes 24 of a shaft member 23. This application of a voltage is based on the piezoelectric properties of the shaft member 23, that is, the voltage is applied in such a manner as to form electric fields in directions in which, between adjacent electrodes 24, the shaft member 23 expands at the circumferential part and shrinks at the opposite part and the switching is so made as to cause the expansion and the shrinkage to successively alternate in one direction circumferentially. The shaft member 23 is placed in sliding contact with the inner surface of a bearing 22 so that the friction imparts a rotative force in one direction that rotates the turntable 15. Since the shaft member 23 itself does not rotate, no clearance is required between the shaft member 23 and a through hole 25 therefor so that a seal can be formed by using a sealing material 26 therebetween.

A target number-of-revolution setter 7 sets a target number-of-revolution of the motor 1. A comparator 6 compares an output of the counter N with that of the setter 7. An output of the comparator 6 is input to a voltage controller 8. The controller 8 controls a voltage to be supplied to the motor 1 to set number of revolutions of the motor 1 to a desired value.
